M.E. Simpson Co. is performing the semi-annual unidirectional flushing of the City of Rochester water lines - a process to clean the mains. 

The work will continue for 30 days, weather permitting. 

During this time, the city advises that residents may experience cloudy or discolored water at any time.  The water is however safe to use and drink, according to a city press release. 

Running it longer before use may help clear it, residents are encouraged to avoid washing white clothes while the water is discolored.
